AND C. WV. MERCHANT, OF SAME PLACE.

Letters Patent No. 93,224, dated August 3, 1869.

IMPROVEMENT IN LAMPS.

The Schedule referred to in these Letters Patent and. making part 01 thesame.

To all whom it may concern:

Be it known that I, JOHN PHELPS, of Owego, in the county of Tioga, andState of New York, have invented a new and useful Improvement inLamp-Tops; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reference being had to the accompanyingdrawings, forming part of this specification.

The object of this invention is to provide a simple and efficientarrangement, whereby the filling-orifices through the necks of keroseneand other lamps may be readily opened for filling, and immediatelyclosed on the withdrawal of the nozzles ofthe cans, by a selfclosingdevice, which will keep the passage closed sufliciently tight to preventdanger, and which will not work loose or get out of order.

Figure 1 represents an elevation of a lamp h. ving my improvementattached, and

Figure 2 represents a horizontal sect-ion, of the same.

Similar letters of reference indicate corresponding parts.

I propose to employ a spring-closing band, A, secured to the neck on oneside of the hole at B, and extending around the same, to cover thefilling-orifice O. I prefer to make it of the same width as the neck ofthe lamp, and to make it thicker at the end secured to the lamp, andtapering toward the other end; and I also vprefer to arrange the ring Dat the top of the neck, to project over the top of the ring.

This ring I propose to fit around the neck with great accuracy, in diesor other machinery, capable of making the parts very exact, so that whenin the closed position, the end which closes the orifice will be pressedtightlyau'd accurately against the surface of the neck, surrounding thehole; and in order to prevent springing the free end too far back whenopening it, I provide a stud-pin, E, projecting from the neck through aslot in the end of the spring, the said slot being so placed that theend wall thereof will arrest the movement when the space is uncovered.

F represents a stud-pin projecting from the end of the spring, by whichto force the spring open by the application of the thumb of the lefthand.

As a further means of insuring the close contact of the end of thespring, I provide a slight projection, G,

from the fixed end of the spring, with an inclined inner face, and Ibevel the end of the spring, to wedge in between the said inclined wallof the projection and the neck. I contemplate, however, using the springwithout this, if preferred.

Having thus described my invention.

I claim as new, and desire to secure by Letters Patent- 1. Thecombination, with the neck of alamp having a filling-orifice, G, of aspring-closing band, A, substantially as specified.

2. The combination, with the above, of the projection Gr, arrangedsubstantially as specified.

The above specification of my invention signed by me, this 1st day ofApril, 1869.

JOHN PHELPS.
